China's existing tea processing technology is low in content, product quality is not high, and the added value of products is low, which leads to lack of market competitiveness of products and directly affects the sustainable development of the industry. Drying is an important technological process in the processing of tea. With conventional electric heating, coal-fired boiler equipment is used for drying agricultural products. It requires large amounts of energy to consume large amounts of energy. As a result, the cost of agricultural products increases, and environmental pollution is caused to varying degrees. In response to the traditional problems of low drying efficiency and high cost, Tongyi Air has developed a high-temperature heat pump dryer based on advanced technology and R&D experience. The unit passed rigorous experimental data tests, and all tea drying process indicators met the design requirements. Drying tea leaves with it not only saves energy, safety and environmental protection, saves a lot of labor costs, but also allows the soluble tannic acid in tea to be preserved, which is beneficial to the improvement of tea quality and is deeply loved by tea farmers. At present, Tongyin Air Energy High-Temperature Heat Pump Dryer has begun to be applied in the fields of agriculture, industry, textiles and other fields with advantages of energy-saving, high-efficiency, safety, and pollution-free. It has been well evaluated by industry insiders and users. Now, the heat pump drying equipment has gradually replaced the traditional boilers, earth room baking, etc., and has become the middle of the drying industry.
